  • Title: Antiplasmodial activity of three bisbenzylisoquinoline alkaloids from the tuber of Stephania rotunda.
    Author: Chea A, Bun SS, Azas N, Gasquet M, Bory S, Ollivier E, Elias R.
    Journal: Nat Prod Res; 2010 Nov; 24(18):1766-70. PubMed ID: 20981617.
    Abstract:
    Three bisbenzylisoquinoline alkaloids were isolated for the first time from Stephania rotunda tuber. Their structures were elucidated by spectroscopic methods and their antiplasmodial activity was investigated in vitro on chloroquine resistant Plasmodium falciparum strain W2. These alkaloids were identified as 2-norcepharanthine (1), cepharanoline (2) and fangchinoline (3). In vitro, they displayed significant antiplasmodial activity with inhibitory concentration 50 values of 0.3, 0.2 and 0.3 µM.
